A 12 inch mattress offers a comfortable balance of support, cushioning and value for a wide range of sleepers. Its added height creates room for multiple comfort layers, such as memory foam, TEMPUR-Material™, latex or quilted foam, along with supportive coils in a hybrid mattress. This construction can help cushion pressure points around the shoulders and hips while promoting more even weight distribution and proper spinal alignment. Side sleepers often appreciate the extra contouring of a 12 inch memory foam mattress, while back and combination sleepers may prefer a medium-firm hybrid mattress with responsive support and easier movement. A 12 inch mattress can also provide a substantial feel without the excessive height of an extra-thick mattress, making it a versatile choice for many bedrooms. Before choosing a 12 inch mattress, consider your preferred firmness, sleeping position, body type and whether you share the bed with a partner. A 12 inch hybrid mattress may offer a helpful combination of pressure relief, airflow, bounce and edge support, while an all-foam mattress can provide motion isolation and a more contouring feel. Make sure your bed frame or foundation is designed to support the mattress and check the total bed height after adding sheets, a mattress protector and bedding. Deep-pocket sheets may be useful for a taller mattress, and comparing trial periods, warranties and available comfort options can make it easier to find the right fit. With the right materials and support system, a 12 inch mattress can help create a comfortable sleep setup and make sleep easy™
